I stared work on Solaris integration and after few minutes play, pgadmin

Reproduction scenario:

1) open Query editor
2) switch to query builder
3) clink e.g. on schema
4) close query editor
5) click on "No save"
6) do it again
7) analyze core file.

There is also bug in help. Green plum help does not point on correct
webpage.
